Abstract
Continuously travelling tows of artificial filamentary products obtained by spinning solutions of vegetable seed globulins or phospho-proteins in aqueous alkaline or other aqueous solvent media into acidified saline coagulating baths, are insolubilized by advancing the tow through a tubular passage by means of a turbulent stream of an aqueous formaldehyde solution saturated with sodium chloride and containing sodium sulphate or magnesium sulphate and having a pH of 4 to 6, and then advancing the treated tow through <PICT:0637025/IV (a)/1> another tubular passage by means of a turbulent stream of an aqueous formaldehyde solution strongly acidified with sulphuric acid and saturated with sodium sulphate or magnesium sulphate, this second solution being at a higher temperature than the first. The vegetable seed globulins may be peanut proteins, and the phospho-protein may be casein. The tubular passage is preferably of narrow diameter and may be either straight or arranged in helical form, but in both cases the liquid is passed through under such conditions as to be in turbulent flow. In the example, a matured caustic soda solution of groundnut globulin prepared from a solution containing peanut globulin, caustic soda and sodium sulphite is extruded through a spinneret 1 into a coagulating bath 2 containing sodium sulphate and sulphuric acid. The resulting tow 3 is then stretched between godets 4 and 5 and led over godet 6 through a device 8 having a reciprocating motion radial to the centre of the ring trough 7 and into the trough, which contains a saturated acidified solution of sodium chloride. The tow is taken up and stretched between godets 1 and 12, passed over godet 13 and then through a vertical helical coil 15 through which a formaldehyde solution saturated with sodium chloride and containing sodium sulphate is passed at 70 DEG C. After stretching between godets 17 and 18 the tow is passed through another helical coil 20 containing a formaldehyde solution acidified with sulphuric acid and saturated with sodium sulphate at 95 DEG C., and is finally washed and dried. Specifications 513,910, 597,497 and 623,460 are referred to.
